Grant isn't sure how much damage he inflicted on the shark, but he was able to flee once it let go. Once ashore, he took off his borrowed wetsuit and saw a few bites measuring up to two inches across.

Grant called out to his friends, but they didn't believe he'd been attacked by a shark. Later, they were shocked to find that the junior doctor had patched himself up with a first-aid kit they'd brought along for their pig-hunting dogs (must be a New Zealand thing).

Helen Collins

In April 2012, 81-year-old John Collins suffered a heart attack while flying his small plane over Wisconsin. His wife, Helen, 80, was in the passenger's seat. Helen had no pilot's license, and had only undergone basic take-off and landing training thirty years prior.
But with fuel running low and the right engine out, Helen calmly landed the plane, with assistance from aviation officials. Tragically, John Collins passed away that day. Helen suffered a back injury and cracked rib, and has since gained national attention for her unbelievable poise and control.
